To all whom it concern: o

Beit known that I, JEANBAPTIsTE MARTIN, a subject of the King of Great Britain, residing at St. Polycarpe, county of Soulanges',` Province of Quebec,"0anada, have invented certain new and useful Improvements in Com'- bination-Derricks; andv I do hereby declare that the following is a full, clear, and exact description of the invention, such as willenro able others skilled in the art to which it appertains to make and use the same. r

My invention relates to an improved hoisting apparatus of the derrick type, combined with a windlass attachment of special adaptability. i i

The object of my invention is to produce an interchangeableV apparatus which may` bel used for a varietyV o f purposes and whichV when not in use may be folded up andknocked down in condition for easyhandling and shipment. 1

One feature of this invention consistsin the construction of the derrickLbeams, which are in the form of a pair of l shear-shaped mem- 2 5 bers pivoted at their upper ends and adapted to be removably secured at'- their lower ends to the base-frame, which carries the windlass.

Another feature of my improvement resides in the mounting of the base-,frame and the provision of means for securing the upright derrick-frame thereto, this frame being further provided with suitable. rollers, which enable the apparatus to be readily shifted, and the longitudinal beams thereof being provided with rearwardly-projecting handles,so that the same may be managed and rolled from place to place'in the same mannerlas an` -beams 9, as shown at 20, and-,securely bolted ordinary wheelbarrow or hand-truck.

Other objects and novel features ofmy in-` 4o vention will appear from the following description and are particularlybrought out in,

the claims. f l

The invention consists in the combination and arrangement of parts hereinafter set fort-h and claimed.

I have shown the most approved form of myimproved derrick apparatus in the accompanying drawings, wherein- Figure 1 is a perspective view of the appa- 5o ratus complete. Fig. 2' is a plan view of the base-frame, showing certain portions thereof in section. Figi?) is. a vertical central section'of the apparatus in position forli'oisting. Fig. 4 is` a separate'perspective View of the upright frame,"a"nd Fig. is a partly-sectional elevation showing the application of the windlass to a horizontal drawing'operation.

The same numerals of reference denote like parts in all theiigures of the drawings.

Myimproved apparatus consistsin the main 6o of two separable framesthat is to say, an

iupright frame 6' and a base-frame '7--the former of which consists, as shown in Fig. 4, of a double pair of"shear legs', eachv consisting of strut-posts 8 and tie-posts 9, pivoted to- 654 gether at their upper ends by a transverse bolt 10, which passes from side to side and through the center of a`roller 11, which acts to retain the two members of each pair of shear1egs at the'proper distance apart. The 7o twomembers 8 of, each pair are appropriately connected together, by cross-'beams 12, and the two tie members 9 are likewise connected by cross members 13, and -each of` the members 8 and 9 is appropriately recessed or mor- 75 i tised, as shown `at 14 and 15, toenable` the two members 8 and 9 of each pairto be folded together and laid flat ona car or vehicle when `it is desired to transport the derrick or .to

prepare it for sl'iip'm'ent. The two strut-posts 8o 8 are each providedat their lower ends with a downwardly-projectingnpin 16, whichis adapted to be seatedin asuitable socket 17, Vformed at the front endofv one of the longitudinal side beams 18: of the base-frame 7, 85 and the lower endsof the yti memberS'Qare likewise provided with 'a pair of hooks 19, which are passed transversely through the thereto by nuts 21 passing o ve'rtheir threa'd- 9o ed ends. These hooks 19 dependioalevel ,with the'loweigrnds of the'members 9', which upon the base-frame, I furthermore preferthey are connected by the axle 30 of a pair of truck rollers` or wheels 3l, having flattened :rims or fellies 32, whereby to offer a wide area to sustain the upright frame and prevent the wheels 31 from crushing into the ground when the apparatusis rolled along. On the rear-ends of the beams 13 are formed a pair of handlebars 33, by which the rear end of the appa ratus is adapted to be raised and turned about the axis 30 in the manner of an ordinary hand-truck or barrow when it is desired to roll the derrick from place to place. On the upper side of this base-frame, just in the rear of the upright frame, is mounted a windlass, which comprises a winding-drum 34, mounted upon an arbor 35, journaled in a pair of pillow-blocks 3G, secured upon the respective beams 1S by holding-down bolts 37. To the ends of the drum are securely attached ratchet-wheels 3S, which are engaged by dragpawls 39, pivoted at 40 upon hand levers or bars 41, which levers or bars are themselves mounted to turn loosely upon the arbor 35. The weight of the pawls 39 holds them in contact with the teeth of the ratchet-wheels 38 and causes them to slip thereover when the lever-bars 41 are raised, and in order to enable a weight raised by the derrick to belowered I provide levers 42, which are pivoted, as at 43, to straps 44, mounted upon the levers 4l, and connected, as at 45, to the pawls 39, so that by pressing down upon the rear end of the lever 42, which is arranged to be operated by the hand resting upon the lever 41, the pawl 39 can be raised.

In order to provide further against the back turning of the ratchet-wheels 38 and to support a weight in any given position, I also preferably provide upon the lower side of the ratchet-wheels a pair of stationary pawls 4G, which are pivoted to the beams 18, as shown at 47, and spring-pressed against the teeth of the ratchet-wheels by means of suitable leafsprings 48. `When the apparatus is in use as a derrick, a cord or other connection 49 is wound around the drum 34 and secured atene end thereto and thence passed upwardly and around the roller 11, from which it is let down, and may have a suitable grapple, such as a pair of sister hooks 50, attached to the lower end thereof to seize and raise any desired weight 51.

In case it is desired to produce a horizontal draft upon the connection 49 the upright frame maybe removed by tipping it backwardly until the hooks 19 are disengaged from the eyebolts 23, when the derrick may be removed, and in order to secure or anchor the windlass-frame against horizontal displacement, due to the reaction of the rope 49, I provide a pair of downwardly-projecting spikes 52, which are braced by bracket-irons 53 and kproject from the lower side of the beams 1S.

In Fig. 5 I have shown this application of my apparatus in the operation of drawing a freight-car 54 alongthe track 55, which is done by engaging the hook 56, carried by the end of the rope 49, with the draw-link 57 of the car and anchoring the spikes 52 behind one of the ties 58, the base-frame being caused in this case to rest in the center of the track, between t-he two rails thereof.

The operation of winding the cord 49 about the drum 34 may be done by two men, each working at one of the hand-levers 41, and in cases where the force upon the rope is not too great these hand-levers will ordinarily be worked alternately, so as to produce a continuous rotation of the drum 34; but where the reaction of the rope is very great the two operators will depress their respective levers simultaneously, so as to produce double the power that could be produced by one lever.

From the above description the numerous advantages of my combination-derrick will be obvious, as well as its ready adaptability to all conditions and the ease with which it may be knocked down for shipment, as well as transported in mounted position from place to place.

While I have shown in the accompanying drawings the preferred form of my invention, it will be understood that I do not limit myself to the precise form shown, for many of the details may be changed in form or position without affecting the operativeness or utility of my invention, and I therefore reserve the right to make such modifications as are included in the scope of the following claims.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, isp 1.
